Silver halide emulsion |
(57) The present invention provides a silver halide emulsion showing high sensitivity
andhigh image quality, which comprises water, a dispersion medium and silver halide
grains, wherein from 60 to 100% of the total projected area of the silver halide grains
are tabular grains having: an aspect ratio (projected area diameter/thickness) of
from 2.6 to 300; AgI content (mol%) of from 88 to 100; and a projected area diameter
of grain (µm) of 0.2 to 10, and the tabular grains have from 3 to 10
4 planes per a grain of twin defect plane parallel to the main plane.
